Austrian Digital Terrain Elevation Model from Airborne Laser Scanning

A 1-meter resolution digital terrain model (DTM) of Austria, representing the bare earth surface without vegetation. The data was collected using airborne laser scanning (ALS) technology and is provided as a georeferenced grid in the European coordinate system. This dataset is one of 55 tiles that collectively cover the entire territory of Austria.

Use Cases

• Flood risk modeling based on the detailed terrain elevation.
• Civil engineering and construction planning based on the bare earth surface model.
• Environmental and hydrological analysis based on the natural soil elevation grid.
• 3D terrain visualization and mapping based on the 1-meter resolution DTM.

Strengths

• High 1-meter spatial resolution for detailed terrain analysis.
• Covers the entire territory of Austria across 55 tiles.
• Represents the bare earth surface, excluding vegetation, as a digital terrain model.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
• Data may reflect geographic bias inherent to the specific ALS survey methods.
